Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Primary Objective:

To demonstrate the non-inferiority of the seroprotection rate (serum bactericidal assay using human complement \[hSBA\] titer greater than or equal to \[\>=\] 1:8) to meningococcal serogroups A, C, W, and Y following the administration of a single dose of Meningococcal Polysaccharide (Serogroups A, C, Y, and W) Tetanus Toxoid Conjugate vaccine (MenACYW Conjugate vaccine) (Group 1) compared to a single dose of Nimenrix® (Group 2).

Secondary Objective:

To describe:

* the antibody response of meningococcal serogroups A, C, W, and Y measured by hSBA, before and 1 month following meningococcal vaccination administered alone (Groups 1 and 2) or concomitantly with 9-valent human papilloma virus (9vHPV) and tetanus, diphtheria, and acellular pertussis - inactivated polio vaccine \[adsorbed, reduced antigen(s) content\] (Tdap-IPV) vaccines (Group 3).
* the antibody response of meningococcal serogroup C measured by hSBA and serum bactericidal assay using baby rabbit complement (rSBA), before vaccination and at Day 31 after vaccination with MenACYW Conjugate vaccine or Nimenrix® (Groups 1 and 2) according to MenC primed status.
* the antibody response against antigens of 9vHPV and Tdap-IPV vaccines, before and 1 month following vaccination.
* the safety profile in each group after each and any vaccination.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The duration of study participation for each participant was approximately 30 to 60 days, including 2 or 3 visits (1 or 2 vaccination visit) and 1 or 2 telephone calls, depending on study Group.

\* This was the first dose of 9vHPV, of the 2-dose or 3-dose series according to the local recommendations and age of the participant. These additional vaccinations for the completion of 9vHPV schedule took place outside of the objectives and scope of this study and thus were not described in this protocol.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

This was a parallel group prevention study with 2 groups that were observer blind (only the person administering the vaccine was unblinded), and 1 group that was open-label.
Primary Study Purpose

TREATMENT

Blinding Strategy

QUADRUPLE

Participants Caregivers Investigators Outcome Assessors
The study was performed in a partially observer-blind fashion:

In Groups 1 and 2

* Investigators and study staff who conducted the safety assessment, participants, parents/legally acceptable representatives, the Sponsor, and laboratory personnel performing the serology testing were kept blinded to the vaccine received.
* Only the study staff who prepared and administered the vaccine and were not involved with the safety evaluation know which vaccine was administered.

In Group 3

\- Everyone involved in the study (i.e., Investigator, study staff, the Sponsor, participants, parents/legally acceptable representatives) know which vaccine was administered. This open-label design for Group 3 was due to the different vaccination schedule for this group than for Groups 1 and 2.
